Specification of Letters Patent.

' Application filed December 16, 1919. Serial No. 345,385.

Connellsville, in the county of Fayette,

State of Pennsylvania, have invented a new and useful Heater; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to heaters particularly designed for residential residences and has for its objectto provide a heater or furnace wherein coke may be utilized for heating the products of combustion passing outwardly from the furnace at the upper end thereof into horizontally disposed flues which flues are bent upon themselves so as to form a series of horizontal flues, the lower ends of said flues being connected to each other and terminating in a reduced extension through which the products of combustion pass to a chimney. The reduced outlet insures the proper burning of the coke and also prevents the rapid burning thereof.

A further object of the invention is to provide a downwardly extending flue arrangement for a furnace comprising a pair of fines formed so as to provide horizontal flue portions in communication with each other and having their lower ends joined together so as to form a common outlet. The downwardly extending flues being particularly adapted for use with a furnace where cokeis used as a fuel and also by the particular construction of the fines, causing an intense heat to be radiated from the walls of the fiues and the furnace into a compartment formed around the furnace and the fines by a casing, from which compartment the heat may be conveyed through suitable piping to various parts of the building.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth shown in the drawings, described and claimed, it being understood that changes in precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a perspective view of the furnace looking at the same from the rear, the collecting casing being removed.

Fig. 2 is a side elevation of the furnace and its flues, showing the collecting casing in longitudinal section.

Fig. 3 is a plan view of the furnace and fines, showing the heat collecting casing re: moved.

Fig. 1 is a detail perspective view of a portion of the rear wall of the furnace showing the flue openings therein, said view being taken from inside of the furnace.

Referring to the drawings, the numeral 1 designates a conventional form of'furnace and 2 the rear wall thereof. Extending through the rear wall 2 are openings 3, through which the products of combustion from the furnace pass into parallel horizontal pipes 4. The pipes 4 are provided with flanges at their ends and through the flanges 9, bolts 10 pass for securing the pipes to the rear wall 2 of the furnace and in registration with the openings 3. Secured to the outer ends of the pipes 4: are depending reversely positioned elbows 11 to which are secured reversely depending elbows 12, the elbows 11 and 12 are secured together by means of bolts 13, which pass through their engaging flanges. The flanged ends 14: of the upper elbows 11 are secured to the pipes 4 by means of bolts 15 which pass through the flanges of the pipes 4c and the upper flanges of the elbows 11. A horizontally disposed elbow 16 is secured to the lower end of the elbows 12 by means of bolt 17 and is provided with a reduced common outlet 18, through which the products of combustion from the furnace pass to any suitable point of discharge after they have passed through the circuitous passages formed by the pipes 41-, elbows l1 and 12 and the horizontal elbow 16. The reduced common outlet 18 retards to a certain extent the passage of the products of com bustion and in connection with the downwardly extending passage through the pipe 4 and elbows sufficiently retards the pas sage of the products of combustion so that the coke will not burn too rapidly. It has been found that where the products of combustion pass from the furnace in an up ward direction, or in a horizontal direction only that the coke burns so rapidly that it is impractical to use the same for heating purposes. The common outlet 18 may lead to a chimney or to any other point of discharge desired. Surrounding the furnace and the elbows and pipes l is a collecting casing 19 for the heat radiated from the furnace, the pipes 1 and elbows, said heat being conveyed through pipes 20 to any desired part of the building.

Pivotally mounted on the pipe forming the common outlet 18 is a cross connecting member formed from piping and comprising a pipe section 22 which is pivoted on the pipe of the common outlet 18, a vertical portion 23 and a second pipe section 24 which is adapted to be placed into engagement with either reduced stub pipe 25 or 26. If the heater is being used so as to get the maximum heating radiation into the casing 19, the pipe section 24: is placed in engagement with the reduced stub pipe 25 of one of the upper elbows 11 and the other stub pipe 26 of the other elbow 11 is closed by the cap 27. Disposed within the stub pipe 25 is a damper 28, said damper being controlled by an opcrating rod 29, which extends forwardly and is disposed in front of the furnace.

It will be seen that the products of combustion as they leave the furnace will pass through the circuitous passages formed by the pipes 41-, elbows 11 and 12 and elbow 16, and be discharged into the pipe section 22 of the cross connecting member through the common outlet 18. The damper 28 being closed, the products of combustion will pass upwardly and be discharged into a chimney through the discharge opening 30. The common outlet 18 is of a reduced size in relation to the interior diameter of the passage for the products of combustion and it will be seen that the passage of the products of combustion will be choked at this point, thereby allowing the slow and even burning of the coke within the furnace. This burning may be increased or decreased by manipulation of the damper 28 by means of the operating rod 29. If it is desired to form a direct passage of the products of combustion to the chimney, the damper 28 is opened so that the products of combustion will pass through one of the pipes 4, the upper half of its elbow 11, thence through the stub pipe 25 and may be discharged through the outlet 30 through the right angle portions 2 1 of the cross connecting member. However, in this direction passage of the products of combustion it has been found necessary to prevent the too rapid combustion and burning of the coke within the furnace and to overcome this difficulty, especially where coke is used as a fuel, extension 25 has the opening therethrough of a smaller diameter than passage with which it communicates thereby forming a choking of the products of combustion, which will, to a certain extent, prevent the toorapid burning and combustion of the fuel within the furnace. By forming the device as set forth above from a series of elbows, it will be seen that the combustion passages may be easily and quickly cleaned by inserting a tool into them through the stub pipes 25 and 26 and working the soot and other foreign substances downwardly into the lower branch pipe 16 from which elbow the soot and dirt may be easily removed through the common outlet 18.

The invention having been set forth what is claimed as new and useful is 1. The combination with a furnace disposed within a heat collecting chamber, of a pair of parallel horizontal pipes secured to the upper end of the furnace, reversely p0- sitioned elbows depending from said parallel horizontal pipes, a U-shaped horizontally disposedL branch pipe connected to the lower elbow and provided with a reduced common outlet, stub pipes in the bends of the upper elbows, a pipe pivoted to the reduced common outlet pipe of the branch pipe, means whereby said pivoted pipe may be connected to either stub pipe in the bends of the elbows as desired and means whereby the passage of the products of combustion to the pivoted pipe through the stub pipe may be controlled.

2. The combination with a furnace disposed within a heat collecting chamber, of a pair of parallel horizontally disposed pipes secured to the upper end of the furnace, rcversely positioned elbows depending from said parallel horizontal pipes, thereby forming downwardly extending circuitous passages for the products of combustion, the lower ends of the lower elbows being connected together by a horizontally disposed branch pipe, a reduced common outlet carried by said branch and centrally disposed thereon, a pivoted pipe connected to the com.- mon outlet, reduced stub pipes carried in the bends ofthe upper elbows and adapted to be connected to the upper end of the pivoted pipe as desired, means for controlling the passage of the products of combustion through the reduced stub pipe to which the upper end of the pivoted pipe is connected and means whereby the stub pipe of the other elbow may be closed as desired.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
